MAMMALIAN REMAINS FROM A LATE 

 TERTIARY FORMATION AT 

 IRONSIDE, OREGON 



BY 



JOHN C. MEEKIAM 



INTRODUCTION 



In December, 1915, Dr. W. D. Matthew of the American Museum 

 of Natural History kindly called the attention of the writer to a 

 reported occurrence of fossil mammalian remains at a locality near 

 Ironside. Malheur County, Oregon, the information having come to 

 Dr. Matthew through Mr. H. E. Anthony, of the Department of Mam- 

 malogy and Ornithology in the American Museum. In subsequent 

 correspondence Mr. Anthony informed the writer that a number of 

 specimens had been obtained by his father, A. W. Anthony, at various 

 localities in Malheur County, Oregon. In later correspondence, Mr. 

 A. W. Anthony kindly furnished to the writer such information 

 regarding the localities as was available. These discoveries suggested 

 the occurrence of a fauna of importance in consideration of the history 

 of mammals in the northern portion of the Great Basin province, and 

 the writer accepted the invitation of Mr. Anthony to visit the Iron- 

 side region and examine the fossil-bearing formation. 



In company with Dr. J. P. Buwalda of the University of California 

 the writer had the opportunity to make a hurried survey of this region 

 in June, 1916. The writer desires to express his appreciation of the 

 courtesies extended by Mr. and Mrs. Anthony during the visit to 

 Ironside, and for several interesting mammal specimens presented to 

 the University by Mr. Anthony. It is also a pleasure to acknowledge 

 the courtesy of Dr. Matthew and Mr. H. E. Anthony in furnishing 

 the original information leading to investigations of this locality.
